Preservation of sedimentary organic matter through natural sulfurisation: An overview. Mineralog

Abstract

Natural sulphurisation is an important pathway for the preservation of OM, especially in marine sediments. Natural sulphurisation is an early diagenetic process and may occur with both lipids and carbohydrates. It results in the formation of sulphur-rich kerogens which generate petroleum at a lower thermal stress than sulphur-poor kerogens.
